Brazil has sent heavily armoured military vehicles into a slum in Rio de Janeiro in a major escalation of the government's fight against drug related crime in the city's shantytowns.
Police said on Thursday that drug gang leaders have been seen fleeing the Vila Cruzeiro slum as Brazilian authorities work to "retake" the area.
"At this moment, Vila Cruzeiro belongs to the state," Rodrigo Oliveira, a police spokesman, said.
More than 17,000 police officers have been deployed across the city, and at least 30 suspected drug traffickers have been killed since the operation began on Sunday, police officials said.
